POWDER DISPENSING DEVICE Filed Sept. 22, 1964 INVENTOR Fl 6 3 NOCIChBerger ATTORNEY United States Patent 3,59,7 33 POWDER DISPENSING DEVICENoach Berger, 12325 82nd Ave., Kew Gardens 15, N.Y. Filed Sept. 22,1964, Ser. No. 393,175 7 Claims. (Cl. 222193) This invention relatesgenerally to powder dispensing devices and more particularly to acompact dispensing unit especially suitable to the ends of ejectingcosmetic, deodorant or dessicant type powders into cramped orhard-to-reach places, the unit being further conveniently shaped forhandling and carrying purposes.

According, and consonant with the foregoing, the instant invention hasfor an object the provision of a powder dispenser which includes asqueeze section connected to the powder-containing section, said squeezesection serving to extend the length of the dispensing unit when thelatter is in the operative position, the length of the unit beingsubstantially reducible in size for convenience of storage thereof.

Another object of the present invention is to provide a powder dispenserof the foregoing character wherein the squeeze section is concealed whenthe device is in the inoperative position whereby the inadvertentdispensation of powder is precluded.

A further object of this invention resides in the provision of a compactpowder dispensing device wherein the squeeze section includes meanswhereby the latter is rendered removably securable in superposition withrespect to the powder-containing and dispensing section.

Another object of the present invention resides in the provision of apowder dispensing device which may be formed extremely thin ofconfiguration and which, therefore, will enable placement thereof withinnarrow and otherwise inaccessible places.

Another general object of the present invention is to provide a deviceof the described character which will be simple in structure, economicalof manufacture, extremely pleasing of appearance, and highly effectivein use.

Other objects and advantages of the instant powder dispensing devicewill be set forth in part hereinafter and in part will be obviousherefrom, or may be learned by practice of the invention, the same beingrealized and attained by means of the structure defined and pointed outin the appended claims.

The accompanying drawings referred to herein and constituting a parthereof, illustrate one embodiment of the invention, and together withthe description, serve to explain the principles of the invention.

FIGURE 1 is a perspective view of the powder dispensing deviceillustrated in opened operative form;

FIGURE 2 is a side elevational cross-sectional view of the device shownin opened operative position;

FIGURE 3 is a side elevational cross-sectional view of the device shownin closed inoperative position; and

FIGURE 4 is a view taken along line 44 of FIGURE 2.

Referring now in detail to the present preferred embodiment of theinvention illustrated in the accompanying drawings, FIGURE 1 shows thepowder dispensing device designated generally by numeral 1, thepartially unfolded position thereof being illustrative of the flexibleconnection provided between the body sections of the device as moreparticularly described hereinbelow.

As more specifically disclosed in FIGURES 2 and 3 of the drawings, saiddevice is comprised of first and second hollow body sections 2 and 4,respectively, said sections being sealingly and flexibly connected atcommon end region 6, the latter being disposed substantially centrallyof the device when arranged in the completely opened position shown inFIGURE 2. Apertures 8 are 3,199,743 Patented Aug. 10, 1965 provided asshown through said common end region to thus provide communicationbetween the hollow interiors of said sections.

The entire device is preferably constructed of plastic such as styreneor phenolic resin although metal, wood or other suitable material,natural or synthetic, may be utilized.

Hollow body section 2 includes a pair of rigid opposing wall surfaces 9and 10, section 4, however, being comprised of a rigid Wall 12 and aresilient opposing wall 14, the latter being formed of relatively thinpolyethylene or rubber whereby when depressed by the finger of the userthe volume of chamber 16 of section 4 will be decreased to thereby forceair contained therein into chamber 18 of section 2 via apertures S. Thepowder 20, upon depression of wall 14 as shown in broken linedesignation in FIGURE 2 will as expected, force powder through openings22 which constitute discharge ports provided through the free end 24 ofsection 2. Air vent 26 is provided through the side wall 27 of section 4as shown in FIGURE 1, said vent being sufliciently small so as not torelease the air being squeezed out of section 4 when wall 14 isdepressed, but to rather permit the hollow chamber 16 to be slowlyreplenished with air upon release of said wall 14.

As shown in FIGURE 3, sections 2 and 4 are foldable at common end region6, the materials uniting said sections at the common end region beingflexible to hingedly relate said sections thereat whereby said sectionsmay be arranged to superpose one another. Accordingly, in accordancewith this disclosure, the placement of said sections into mutualsuperposition will form a compact unit as illustrated in FIGURE 3 of thedrawings, wherein the resilient wall 14 will be disposed contiguouslywith respect to rigid wall surface 9, resilient wall 14 being therebyprotected against inadvertently applied pressures which would result indischarge of powder through said discharge ports 22.

As shown in the drawings end 31 of section 4 is provided with alaterally extending portion 28 adjacently of resilient wall 14 andsubstantially at a right angle therewith, said portion 28 being aclosure cap which overlies said discharge ports to preclude dischargetherefrom when said sections are mutually superposed.

The arcuate configuration of said closure cap 28 enables a complementingfitting relation between said cap and the convex configuration ofaforesaid end 24. It will be appreciated that the shape of the closurecap and of end 24 as well may be varied for aesthetic purposes withoutinterfering with the functional ends thereof.

A catch type fastener 39 is provided as shown at the extremity of theclosure cap, said fastener being receivable within indent 32 providedwithin wall portion 34 of section 2, and serving to retain said sectionsin the mutually superposed position shown in FIGURE 3.

To permit chamber 18 of section 2 to be loaded with powder, filler plug36 is provided, said filler plug being threadedly received within Wall 9of said section 2. It will be understood that said plug may be pressfitted in lieu of the threaded arrangement shown.

Although the preferred embodiment of the powder dispensing devicestructure has been described, it will be understood that within thepurview of this invention various changes may be made in the forms,details, proportion and arrangement of parts, the combination thereofand mode of operation, which generally stated consists in a devicecapable of carrying out the objects set forth as described and definedin the appended claims.
